Har-Tru hardcourts quietly anchor the US Open Series
Jun 25, 2026
When tennis fans think of the summer swing, they picture blistering forehands, high humidity, and the intense competition of the hardcourt season. As the world’s best players battle for points and momentum ahead of the final Grand Slam of the year, every variable matters. But while players, coaches, and cutting-edge racquets usually take the spotlight, the literal foundation of the sport often goes unnoticed.
Mention the name "Har-Tru," and most tennis aficionados immediately picture the iconic green clay that has defined American tennis for decades. However, a quiet revolution has taken place on the professional tour. Har-Tru is playing a critical support role in the summer season for both the ATP and WTA tours.
The company’s premier hardcourt product, Proflex high performance surfaces, is the trusted court system for an impressive three out of the eight prestigious tournaments in the US Open Series.
The Mubadala DC Open, the historic Cincinnati Open, and Canada’s premier National Bank Open have all chosen Har-Tru’s Proflex acrylic system as their surface of choice. Hosting an ATP and WTA 1000-level event requires flawless execution, and tournament directors can’t compromise on the quality and reliability of their courts.
"We are pleased to be working with Har-Tru as our official court surface provider," said Bob Moran, Tournament Director of the Cincinnati Open. "It's an extremely important step for us to be aligning with Tennis Canada and Washington, D.C., to provide the players a consistent speed and surface for the summer swing of the ATP and WTA Tours."
The Proflex system is designed to deliver maximum consistency, medium-fast pace, and a consistently true bounce—crucial factors for top-tier athletes dialing in their timing. The multi-layered acrylic formulation is calibrated to ensure that the surface plays the exact same way on center court as it does on the outer practice courts.
Furthermore, Proflex offers durability against the intense summer sun and heavy, aggressive foot traffic. Its vibrant, UV-resistant pigments ensure that the courts look as stunningly bright on championship Sunday as they do on opening day, providing bright contrast for both the players and the global television broadcast.
The US Open Series is the ultimate proving ground, not just for the athletes, but for the equipment they rely on. By anchoring nearly half of the series, Har-Tru has decisively proven that its expertise extends far beyond clay. Whether you are outfitting a world-class stadium, a college facility, or a private club, Proflex delivers tour-tested excellence.
